Eb 9/08; E05c 21/00 U.S.Cl. 292-1 1 Claim ABSTRACT OF THE DISCLOSURE A lock mounting to receivea lock set in a door stile having parallel usually upright side surfacesand a usually upright end surface merging with the side surfaces, themounting including surfaces that can be characterized by the movement ofa generatrix such as a right line always moving parallel to itself andnormal to said side surfaces and travelling through said end surface toafford break-out edges, all of said surfaces together defining a socketto receive at least part of a lock set.

My invention relates to the environment of lock units, usually a doorpanel or door stile mounted to swing about the vertical axis of hingeswhich hold the-'door panel in a door frame with the meeting portions ordoor stile and door jamb slightly spaced apart. Lock units are mountedin the door panel in a number of different ways, yet there is always aneed for improving the mounting of the door lock unit. In some instancesa bore is provided through the material of the door panel from one sideto the other at a distance spaced from the door edge face and anotheropening is bored from the edge face to intersect the first bore. A lockunit is then assembled within the two bores and interconnected for use.A certain precision is required for this operation.

It is therefore an object of my invention to provide a lock mounting inwhich the door panel is prepared in an improved fashion to receive alock unit, especially a lock unit assembled prior to mounting on thedoor panel.

Another object of the invention is to provide a lock mounting in whichthe door panel is adapted to receive the lock mounting with little or nochance for error in configuration of the lock receiving portion and inwhich the amounts of skill and labor required are small.

Another object of the invention is in general to provide an improvedlock mounting.

Other objects together with the foregoing are attained in theembodiments of the invention described in the accompanying descriptionand illustrated in the accompanying drawings, in which:

A lock mounting of a somewhat related character is disclosed in mycopending application entitled Lock Mounting filed Feb. 23, 1967 withSer. No. 618,055 and assigned to the assignee hereof.

In this instance the lock mounting is particularly for use in a doorpanel 6 herein diagrammatically represented simply by a rectangularblock. This is intended to show the immediate environment of a lock unitwhich is normally mounted on a door designed to swing about hinges witha vertical axis. The door or block has a pair of parallel, generallyplanar side faces 7 and 8 extending parallel to the hinge axis. The sidefaces merge with a planar edge face 9 extending vertically or parallelto the hinge axis and is approximately or exactly normal orperpendicular to the side faces 7 and 8. In some instances the edge face9 is not exactly perpendicular to the side faces 7 and 8, being given abevel or curvature, but it is nearly enough to a perpendicularrelationship so that it is characterized herein as being substantiallyperpendicular.

Pursuant to the invention, the mounting in this instance is provided byremoving material from the panel 6 (or in initially forming the panel 6in the event it is molded or cast or is made up of deformable material)to provide a lock socket 11 defined by a surface 12 characterized by themovement of a generatrix always travelling parallel to itself and normalto the side surfaces 7 and 8. The movement of the generatrix can beconsidered as beginning at the edge face 9, travelling into and throughthe door panel 6 in a curved or arcuate path and then emerging orterminating at the edge surface 9. The path is such that the curvedsurface 12 breaks out or merges with the planar edge surface 9 to definebreak-out edges 13 and 14 parallel to each other. This configurationthus affords a mounting for a lock unit occupying the socket 11 withparts projecting therefrom on opposite sides of the surfaces 7 and 8 andwith a projecting latch bolt merging between the break-out edges 13 and14 to project in a direction normal to the edge surface 9. The mountingis characterized by a single defining surface extending from one side 7to the other side 8 and breaking through the edge face 9.

In a somewhat related way the surface 7 in the mount of FIGURE 2 isinterrupted by a channel 16 defined by generally parallel walls 17 and18 generated by the movement of two generatrixes normal to the surface7. Both of the surfaces or walls 17 and 18 emerge through the end face19 of the material in break-out edges 21 and 22 as well as break-outedges 23 and 24. While the channel 16 is in some instances useful as itstands, it is normally altered by removal of material on the inside ofthe surface 18 so that the final result is very much like the socket ofFIGURE 1 except that it does not extend entirely through the block butrather stops at a planar surface 26 parallel to the surface 7.

In FIGURE 3 the arrangement is comparable to that in FIGURE 1 in thatthe generatrix affords a curved surface 31 normal to the side surface 32and having break-out edges 33 and 34. This form of device or mounting isusable as it stands for many forms of lock unit and the surface 31 isreadily formed by various different sorts of tools.

FIGURE 4 is an arrangement comparable to FIGURE 3 in many regards and isalso provided with a curved surface 36 generated by a line moving in acircular path always parallel to itself and normal to the side surface37. In this instance the surface 36 does not extend entirely through theblock, but rather terminates in a planar surface 38 parallel to the sidesurface 37, thus affording three break-out edges 39, 41 and 42. Thecurved surface 36 can be approximately a half circle in extent or evensomething more than that to afford a re-entrant pocket if desired.

In FIGURE the block is provided with surfaces 43 and 44 generated bymovement of a right line parallel to itself and normal to the sidesurface 46 and is one which can be fabricated in a number of differentways. If a rotary tool is used, turning about its own axis parallel tothe generatrix, and the diameter of the tool is quite small, the resultapproximates closely the surfaces indicated.

In FIGURE 6 the path of the generatrix is compound in that a firstcurved surface 51 affords a break-out edge 52 adjacent the end surface53 of the block, and a second curved surface 54 affords a break-out edge56 parallel to the break-out edge 52. The surfaces can be generated by asingle generatrix moving in a compound circular path and afford an apexedge 57 where they merge.

In FIGURE 7 a similar arrangement is had in that curved oppositesurfaces 61 and 62 are generated by the same generatrix operating in acircular path normal to the side surface 63 of the figure. This affordstwo breakout edges 64 and 66. Intersecting the arcuate surfaces 61 and62 is a curved surface 67 which may be circular in configuration and isgenerated by a generatrix moving normal to the surface 63 but aboutanother, parallel axis, so that two ridges 68 and 69 are afforded at thesurface intersections.

In FIGURE 8 a configuration similar to that of FIG- URE 7 is affordedexcept that the opposite surfaces 71 and 72, as well as the surface 73which intersects them, do not extend entirely through the block, butrather end at a planar surface 74 parallel to the side surface 76.

In FIGURE 9 there is disclosed an arrangement in which a circularcylindrical surface 81 extends entirely through the block 82 from oneside face 83 to the parallel side face 84 thereof. The axis of thesurface 81 is substantially normal to the surface 83. An intersectingsurface 86 and an opposite intersecting surface 87 can be generated bythe same generatrix normal to the surface 83 and moving about an axisspaced from the axis of the opening 81. The surfaces 86 and 87 do notextend through either side surface of the block, although they dointersect the edge face 88 thereof to provide break-out edges 89, 91, 92and 93. In addition, where the various surfaces intersect, ridges 94 and96 result.

In FIGURE there is disclosed an arrangement in which a'block 97 havingside faces 98 and 99 is contoured by means of a rotary cutter 101 movingabout an axis at the center of a shaft 102 and advancing in thedirection of the arrow 103. There results a surface 104 which can bedescribed by the rectilinear movement of a generatrix into the material98 from one edge face 106 thereof for a sufficient distance to determinenot only break-out edges 107 and 108, but also generally parallel sideedges 109 and 111 and a curved end surface 112.

In FIGURE 11 there is disclosed an arrangement very much as inthe'preceding figures in which a block 116 such as the stile of a doorand having parallel opposite faces 117 and 118 is characterized by asurface 121 as generated by a generatrix moving normal to the side face117, for example, and moving inwardly from the edge face 122 to leave abreakout edge 123 and emerging to leave another break-out edge 124parallel to the first edge 123 and normal to the plane of the surface117. As an illustration, a lock mechanism 126 is mounted in the stileand occupies the space which has been provided for it and meets thematerial of the stile along the surface 121 between the break-out edges123 and 124, for example.
